As a 50 year old, I can recall a lengthy stretch of time in the US when lamenting the lack of a "white homeland" would not be considered "partisan", but extremely fringe speech that the mainstream would mostly shun.
I think you're right, and I find this revolting. Tech always had its weirdos, but mostly they were kind of idealistic, naive, or had some quirks or otherwise were maybe a bit unique, but they weren't into that kind of flat out evil ideology. Or at least not openly, because there was a sense of shame around that kind of ideology.
